Summary

Nanozymes — nanomaterials with enzyme-like catalytic activity — show promise for degrading microplastics and nanoplastics in food systems through oxidative and hydrolytic mechanisms, including stimulus-responsive designs that activate under specific pH or light conditions. Developing efficient degradation tools is critical given that microplastic contamination has been documented throughout the food chain, from packaging to drinking water.

Microplastic and nanoplastic contamination in the food chain poses growing risks to food safety and human health, while conventional removal strategies remain limited in efficiency and sustainability. Nanozymes, nanomaterials with enzyme-like catalytic activities, have emerged as promising tools for plastic degradation and detoxification. This review summarizes emerging smart nanozyme strategies for microplastic and nanoplastic remediation with a focus on food system applications. We first outline key catalytic mechanisms, particularly oxidative and hydrolytic pathways relevant to polymer breakdown. Advances in intelligent nanozyme design, including stimulus-responsive systems activated by pH, light, or pollutants, are then discussed to highlight performance enhancement and selectivity control. Applications of nanozymes across the food chain, including food processing, packaging, and water purification, are critically reviewed. Finally, biosafety considerations, toxicity regulation, and translational challenges are evaluated. This review bridges mechanistic insights with practical deployment, providing guidance for developing nanozyme-enabled solutions to mitigate microplastic risks in food systems.
